The short, snappy trigger pull. I love the pull of it, it's not really long like the Benchmark's, and it's not near as hard as the AGD stock frame pull. It's purdy looking, no other frame compares to the astonishing looks of the IFrame. INTELLIFEED! People don't realize how much of a miracle this really is, it made a huge difference in my marker, not near as much chopping because the hopper is agitated every shot!

Weaknesses:

Nothing so far, the only thing is that it can be picky with foregrips. KAPP's, System X Gas Thrus, and Fighter X Gas Thru's work.

Conclusion:

Best trigger frame for mags (except E-mag). I would recommend this on top!
